Vasia Kalavri created FLINK-3080: ------------------------------------ Summary: Cannot union a data stream with a product of itself Key: FLINK-3080 URL: https://issues.apache.org/jira/browse/FLINK-3080 Project: Flink Issue Type: Bug Components: Streaming Affects Versions: 0.10.0 Reporter: Vasia Kalavri
Currently it is not possible to union a stream with itself or a product of itself. For example, the following code {{stream.union(stream.map(...))}} fails with this exception: "A DataStream cannot be unioned with itself". The documentation currently states that "If you union a data stream with itself you will still only get each element once." and should also be updated. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
